We recently had a JVM crash during Minor GC.  The hotspot error file and gc
log can be found in attached zip file.  GC settings are:
-Xms350m -Xmx1024m -XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=55 -XX:+DisableExplicitGC -XX:+PrintGC
-XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:RefDiscoveryPolicy=1

We're running build:
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode)

Any ideas what caused the crash?  Some speculate bug 6896647, but it doesn't
seem conclusive.  Any insights would be appreciated.
